Specification of Letters Patent.

Patented Sept. 23, 19.13.

Application filed March 27, 1912. Serial No. 686,593.

.b all whom/1'2 may concern:

Be it known that we, Crmnmcs F. Sounnmnu and JULIUS ITAYMLUY, citizens of the United States, residing at lVaulcegan,

" county of Lake, and State of Illinois, have invented certain new and useful Improvements in Windows, of which the following is a specification.

This invention relates to a novel form of window, which is so constructed that it will permit the proper ventilation of a room without the necessity of a separate, auxiliary ventilating device.

'ihe objects of our invention are to provide a window which is so constructed as to permit fresh air to enter and vitiate or foul air to leave the room without causing undesirable drafts; to provide a. coml'iined window and ventilator; and to provide such a construction which will occupy about the same space as an ordinary window and which will be simple and substantial in construction. We accomplish these objects and various other advantages by means of the window shown in the accompanying drawings, in which;

Figure 1 is a front elevation of a window as seen from within a room; Fig. 2 is a cross sectional. view with parts broken away, and Fig. 3 is a vertical sectional view on an enlarged scale.

As shown in. these drawings, 4: indicates a window frame in which are slidably mounted an upper sash 5 and lower sash (3. These sashes may be counterbalanced by means of any suitable weights, and may be provided with any desired form of catches or looks, such devices being omitted as they form no part of this invention. The lower rail 7 of the bottom sash is preferably made somewhat wider than in ordinary sashes, it being at least sufiiciently wide to extend down to the sub-sill 8, while leaving a border of desired width in View above the stool. lVe provide a strip 9 which extends across the frame adjacent to the lower rail 7 and provide a slide or movable stool 10. This slide or stool is provided with grooves 11, which. are adapted to fit over tongues 12, the latter being preferably dadoed into the jambs 13. This slidable member tits closely above the apron 14 and may be partially supported thereby. It is further supported by screws or bolts 15 which engage with the window frame and pass through holes 16 in the stool 10, the outer portions of these holes being enlarged to receive the heads, thereby providing stops to limit the outer movement of the stool. The outer ends of these holes are preferably plugged as indicated in Fig. 2 to conceal the scrcw heads. The stool or slide 10 is also n'ovided with a linger grip 17.

In the angle formed between the sub-sill 8 and apron 14 is placed a strip 18, which furnishes an air and water brake and insures a tight joint between these members. The outer face of this strip is beveled and the lower edge thereof is provided with a downwardly extending projection 19 which is dadoed into the sub-sill S. The opening formed between the cross piece 9 and the apron 14!: is preferably provided with a screen 20. This screen may be tacked or otherwise secured to the lower edge of the strip 9 and to the upper edge of the st rip 18, as clearly shown in Fig. 3, this forming a convenient means fo' attachment.

-When it is desired to secure the largest amount. of ventilation without having a direct opening under the lower sash, it is raised to about the position shown. in dotted lines in Fig. 3 and the slide or sill 10 is pulled out to its fullest extent. This provides an opening below the sash and the air can pass in through the screen 20 and will be deflected upwardly so as not to cause an objectionable draft in the room. The opening between the check rail of the bottom sash and the cheek rail of the top sash will permit the air in the upper part of the room to pass down and out below the top sash. thereby providing ample means for ventilation. On account of the novel construction and arrangement of our window, the air will pass in without blowing the window shade or causing it to flap to any appreciable extent. Furthermore, the window may be left open in this way without, any danger of rain, sleet, or the like being driven into the room, as the air is suiticient-ly deflected so that under ordinary circum'stances no moisture would be driven up through the open passage way. The amount of air admitted at, the bottom of the window may be regulated by moving the slide or stool 10, so as to increase or decrease the opening. It will also be noted that, on account of the wide bottom rail 7, the stool may be entirely closed and will leave an opening between the check rails, which will permit a certain amount of ventilation. The

slide 10 open and then adjusting the sash 6 so as to increase or decrease the opening underneath the same.

When both the sash and stool are closed, it will be seen that a dead air space is formed in the chamber which. will prevent annoying or undesirable drafts around the bottom of the window. This is a very desirable feature as a comparatively secure closure will he made even if the lower rail of the sash or the stool are not fitted with the greatest accuracy in their slides;

From the above description and the accompanying drawings it will be readily seen that we provide a combined window and ventilator, or what may be termed a ventilating window, by means of which proper ventilation is secured without requiring any additional attachments or without changing the appearance of the window to any con siderable extent. This form of window is not only desirable for houses but for hospitals, vehicles or other places wher proper ventilation is desired.

Having thus described our invention which we do not wish to limit to the exact form or arrangement herein shown and described, except as pointed out hereinafter what we claim and desire to secure by Letters Patent is;

1. A window frame having a chamber in the bottom thereof with openings leading to the outer air and to theinside of a room, a sash having its bottom rail adapted to close the opening to the outer air when the sash is down, and an adjustable stool fitting over the opening leading to the inside of the room and serving to open and close the same.

2. In a window, the combination of a frame, having a sill at the bottom thereof and having an apron engaging with said sill, a sash a cross piece adjacent to the' sash and slightly above the apron, a screen extending between the cross piece and the apron, and a slide mounted above the apron for closing the opening between the apron and the cross piece. 7

3. A window having a'chamber in the bot tom of the frame communicating with the outer air and with the inside of a room, the bottom rail of the lower sash of the window serving to close the outer communication when the sash is down, and means for closing the inner communication.

4. A ventilating window having a chamber in the lower part of the frame, the lower rail of the bottom sash forming one side of the chamber when closed, astrip adjacent to the sash at the top of the chamber said chamber having an opening leading into the room, a screen across said open ing and a slidable stool over said opening.

5; In a ventilating window the combination with the lower sill and apron of a beveled cross piece having a projection dadced into the sill, a second cross piece adjacent.

to the sash and above said sill, a screen be tween said first named cross plece and said second named cross piece, and. a slidable stool mounted above the apron and adapted to close the space between the apron and said second named cross piece. I V
